A 23-year-old gunman accused of killing a boy and critically wounding two of his relatives outside a Colorado dental office has been charged with first-degree murder in what cops are calling an act of road rage.

Jeremy Webster did not have a relationship with any of the victims, the Westminster Police Department said Friday.

Cops say that Webster fled the scene in his vehicle after the shooting on Thursday, but he was later taken into custody.

A total of four people were shot, according to authorities. The slain child's mother and brother remain in critical condition, while a male who is not a member of the family is expected to survive his injuries.

Cops said Friday that the shooting stemmed from "road rage," but did not give more details.
